To azi/whom it may concern Be it imowntnat I, :Casetes W. Boem;

Pittsburgh, inthe County of Aneghenyfand State of Pennsylvania,` have invented certain new and lusefulV Improvements Insect-` Traps, of Which the follotvingis a specification. i

This invention relates to insect `or fly traps, andl anobjec't of thefinvention is to provide a trap which is "comparatively sain*- ple in. construction and by ineens of which flies are enticed into a suitable entrance coin; partlnent, haying communication through l a plurality of relatiyely small lead; openings into a confining compartment, "Wherethey are confined until killed 'or destro ed;

lt is well known that flies tvilla ight upon Wood surfaces, preferably to' inetal, or any other type of surface When Wood surfaces are convenient, and it Visan object of this invention to provide a ily trap as` specified, Hthe bottom of which `is lnade up of a plurality of layers or sections of Wood,'provid1n`g main supporting bottomboard upon which are mounted pluralityof substantially `triangularly Ashaped blocks forn'iing``I sleeves hav-ing constricted outlets Which open i'nto tlie'square space Within the blol's, uf 'on the upper surfaceof the bottoni plate an to mount strips of 'Wood i1-imn the upper surfaces of the said blocks" to provide covers for the open leading spaces and further 'to hingedly connect an entrance lead anda 'cohning member to the `Wooden bottoni struc= ture `of the trap so as to perrnit the removal of the flies' therefroin` after`- the llies have beenkilled ordestroyed; A f

Other objects of the i-nvention Will appear in the following detailed description teilten in connection with the accompanying draW- ingifrining apart Vof this speciiication and in which drawing:

Figure 1 is a perspectiye vieilvfof the ith-f proved fly trap,

Fig. 2 is a cross section through the `fly tmp,

Fig. 3 is a fragmentary horizontal section through the fly trap, and

Fig. 4: is a fragmentary perspective View of a part of the base construction of the trap.

Referring more particularly to the drawings, l indicates the base of thetrap as an entirety, which includes a bottom board 2, being relatively thin, and rectangular in slrape`,` havinga plurality of blocks 3 atl 'cached to upper silrfaces. The facing ends of the blocks 3 arecut at obtuse angles Wlthrespect to the longitudinal lines of the bloel,"so as jto provide lead or entrance openings trhich lead into the space vWithin the inner edges of the blocks These blocks are relatively narrow,` and are attached to the upper surface of the bottom board 2 at the edges of the "saine, by angling the ends of the said blocks, the leads or entrance openings are constricted at their inner ends, foi'fleadingthe insects or flies into the same innvardly of the inner edges of the block.

The bottoni board 2 lhas end strips 4 which are of sllghtlygreater height than the blocks 3 attached to its upper surfacesat its end, and strips o are positioned upon the upper surfaces of the blojclzs, forming closures for the top or upper portions of the entrance opening between the facing ends of the blocks.

A suitable bait may be positioned upon Jche inner surface Vof the bottoni board 2 in the space within theinner edges of the blocks 3,

end stripsill and cover strips 5 forattracting the fiiesinto the said space. A substantially pyraflnidal lead construetion Y is provided, which ineludes longitudinal extending side bars 8 at its loe/er `or base edges and npstanding angularly disposed` sides forlned of if:

screen `or analogous oraminous material, which sci-eeh is 'attached tothe triangnlarly shaped end plate 9 of the sleeve structure '7, the outer end portions of the screen `or forafminous ni'aterial being covered by the binding strips 10. The apex` of the pyramidal lead construction 7 is provided with a plurality of longitudinally spaced openings 11,` to perrnitthe 'enit of the flies from Within tneflead structure `7 inte the cenning cage 12. Theyvire end about tlie'opening 1l eX- tends outwardly into the confining cage 12 forming tongues to retard the'passageof "illes from the confining cage into the lead structure 7.

The confining cage 12 comprises substantially triangularly shaped end pieces 13, which are formed of Wood or analagous Inaterial and have cut out portions 14 at their corners, to receive the longitudinally extending base strips 15 and the longitudinally extending apex strips 16 to which strip is attached the Screen Wire or analogous foraminous material 17 of which the side of the conlining cage 12 is formed. The base strip 15 rests upon the upper surface of the upper strip 5 of the base construction 1 and one of the strips is hingedly connected, bymeans of hinges 18 to the ends of the end stri 4 of the base construction to permit the con ning cage to be swung outwardly from over the sects or ies therefrom.- Thelead 7 is., also hingedly connected, by means of hinges 19 to. the` base structure to permit this lead member to be swung outwardly from over the central space or opening within the base structure 1, for re-baiting the trap or for any other suitable purpose. Suitable hook or catch structure 20 may be provided for holding the free edges of thelead structure 7 andthe confining cag'e 12 connected to` the b ase to prevent the accidental outward hinged movement of these members. Suitable lbinding strips 21 ar-e mounted about the outer surface ofthe screen wire 17 at its ends, binding lthe ends securely in engagement with the upper edges of the end plate or boards 13 of the confining cage 12.

Any suitable bait may be placed upon the upper `surface of the bottom board-.2 within the space centrally thereof, and it will attract the flies or other insects which will enter through the leads or'entrance openings between the `facing angled ends of the blocks 3 and after the'insects have fed, they will, owingA to their natural traits, either fly or walk upwardly through the leads 7 and pass outof the opening l1 into the confining cage 12. When it is desired, any suitable insecticide may be used for killing the insects or flies within the confining cage 12, after which this cage is swung upon its hinges 18 to permit the-removal .of the said insects or flies therefrom. t

Changesin detailsl may be made without departing from the spirit ,of this invention,

- .1. In an insect trap, the combination, of a base structure comprising a bottom board, a pluralityl of-.blocks attached to the upper v surface of said board about its side edges, the facingends of said Vblocks being angled to provide converging lead openings opening outthrough constricted openings into Copies of this patent, may lbe4 obtained for ve cents each, by addressing the Washington, D'. C.

the space between the inner edges of the blocks, a confining cage hingedly connected to said base structure and means to prevent insects escaping from said confining cage.

2. In an insect trap, the combination, of

a base structure composed entirely of Wood base structureto `permit the removal of 1nand comprising a bottom board having end strips extending along its ends, a plurality of base blocks attached to its upper surface along the side edges, the ends of said blocks being cut angularly to provide lead openings the sides of which converge as they extend inwardly, and a confining cage carried by said base structure, and means to prevent the escape of insects from the confining cage.

3. In an insect trap, the combination, of a base structure composed entirely of wood and comprising a bottom board having end strips extending along its ends, and a plurality of base blocks attached to its upper surface along the side edges, the ends of said blocks being cut angularly to provide lead openings the sides of which converge as they extend inwardly, cover strips mounted upon the lupper surfaces of said blocks, a confining cage hingedly connected to said bottom structure and resting upon said cover strips, and means within said confining cage to prevent the escape of insects therefrom.

4. In an insect trap, the combination of a base structure composed entirely of wood and comprising a bottom board having end strips extending along its ends, and a plurality of base blocks attached to its upper surface along the side edges, the ends o1E said blocks being cut angularly to provide lead openings, the sides of which converge as they extend inwardly, cover strips mounted upon the upper surfaces of said blocks and a confining cage hingedly connected to said bottom structure, said confining cage being constructed of foraminous material and having imperf'orate end portions, a substantially pyramidal lead structure hingedly connected to said bottom structure within said confining cage and provided with openings adapted to permit the passage of iies from the lead structure into the confining cage.
